Platform Agnostic Method for Automatic Image Capture (Using Camera)...

edited February 2020 in Xamarin.Forms

Hello,

I'm trying to find a platform agnostic method for taking a set of still images, as fast as a device will allow (i.e. no user interaction) and store each of them in the a gallery / album. I've come across and implemented platform specific methods for doing this (Android and iOS), but want to avoid platform specific code.

Ideally, this process can be initiated via an arbitrary trigger and stopped after an arbitrary amount of time (eg. start a loop that exits when a flag is set). The process should not block pending user action (i.e. is completely automatic). User action elsewhere in the application is fine (actually essential in order to stop the automatic capture process).

Is there a platform neutral way of doing this?

Thanks,

Matthew

    Xamarin.Forms applications typically consist of a shared .NET Standard library and individual platform projects. The platform projects contain any platform-specific logic or packages the application requires.

    Taking photos in Xamarin will call the platform api to achieve the function.

    Is there a platform neutral way of doing this?

    No. You can search for a related plugin or customize a plugin. But for the plugin, the function is still implemented for each platform.

    As I understand it, whilst the implementation may be platform specific, there is a layer of abstraction that one can work with that allows for platform agnostic development. If that is not the case, then what's the point of Xamarin? If I need to develop for Android and iOS independently, then I may as well use Android Studio and XCode respectively. There is already a way operate the camera in a platform agnostic manner using...

    Plugin.Media.CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions() { });

    ...however this requires user interaction to take the picture.

    Hi,

    Regarding camera invoking in android of Xamarin forms.

    I raised my query here: https://forums.xamarin.com/discussion/179458/need-open-camera-without-media-plugin-using-intent-in-android-bind-imagesource-to-source-in-view#latest

    Kindly share your suggestions.

    Based on your sample i need to invoke my BLK camera(leica device) almost like another camera (Eg: YouCamPerfect or any PicEditor)
